My LHS pointed me to Staples they have letters and numbers in all different sizes and colors. I found it easier to buy them instead of trying to cut them out of black trim.
Just so much easier to peel and stick the letters.

You can also find a local graphics shop and get them to produce decals in any font / style you want ...

Shop I use offers in two forms : normal vinyl or the type with front and back support paper .. you peel backing of .. apply and press .. then peel away carrier front paper. That type is extremely thin and excellent for our use.

I paid about $6 for a bagful of decals for couple of models ...

I create the decal in paint or whatever ... word is ok ... in the font I want... I take the file on a flash-drive to them ... they convert to Corel Draw .. size to my reqt's ... couple days later - I collect all the decals ... ready to use.

I used to cut and make own with Solarfilm etc. - but no longer .. above is far better. I also search through Auto Accessory shops for decals .. flames are popular there ! and lining tape.

I did the N-numbers on my just completed Decathlon by printing onto sticker paper from the local Staples. I used white paper with black lettering onto white UltraCote and it blends right in. No cutting out of the individual numbers, just stuck it on as a block and it looks great. I used the same sticker paper, this time over tissue covering, for the roundels and numbers on my Jenny, but those numbers I cut out individually since they went onto a colored background. Pictures of both are on my website.

Here's how I do it using self-adhesive vinyl trim sheets - Monokote has them in matching colors to their covering films. Fonts with straight lines are easiest. If there's anything that's not clear in the pictures please ask. If you need the fonts, let me know. I hope this helps.

I make a name using an online GIMP program like Flamingtext or Cooltext, print it out on decal paper (I use Testors, available at my LHS in both clear and opaque white) and then seal it with a clear paint.Mystique by Szalinski, on Flickr
